Function encode_delta_snapshot_from_updates 

pub fn encode_delta_snapshot_from_updates(
    schema: &Schema,
    tick: SnapshotTick,
    baseline_tick: SnapshotTick,
    destroys: &[EntityId],
    creates: &[EntitySnapshot],
    updates: &[DeltaUpdateEntity],
    limits: &CodecLimits,
    out: &mut [u8],
) -> CodecResult<usize>

Encodes a delta snapshot using precomputed change lists.

This is a lower-level helper. Prefer encode_delta_from_changes with a SessionEncoder for production use.
